I started using this product (Cover Free) this spring and now it's the middle of the summer and not only have I lowered my water bills but my pool is staying warmer then in past years. This is definitely a product that I will continue to use and would highly recommend others to use as well.

I usually get the yellow Solarpill but thought this product would replace it and not have a empty ball in the pool for a day or two. I don't see the sheen from Cover Free that I did from the Solarpill (the one molecule cover). I will not buy again. MKM response: COVERFree, unlike the SolarPill or the Solar Fish, is not isopropyl alcohol based product so it does not create that "sheen" on the surface.
